Ah, here's a "good" question from a detractor who improvises himself as a motorist and wants to give motor lessons to everyone! Such a question just betrays your ignorance of the engine ... and your willingness to deny the benefits of doping ...
My answer? Frankly, what can I say other than this:
Go back to school or buy motor books ...

Thank you for the advice, but the school, I went there a little and enough, I think, to manage to find (and keep, still today) a job in the sector using my acquired knowledge, this is not is not the case for everyone, I believe (In principle, the one to whom the community has paid for training that he has assimilated and if in addition he shows ingenuity, does not take long to be recruited, .. .in short).
And precisely, unlike others, I am not Mr. "I-know-everything-about-engines-and-engine-makers-are-incompetent-or-slow-or-plotters "So I ask myself a few questions and once again, on your part, the only answer is contempt but hey, I'm used to it. Those who do not agree with you must really have a hard time making themselves heard and must quickly become discouraged .... Anyway ... let's get back to the subject ...
I still listened to your advice and I inquired (the answer is not really different from what I thought):

... It should be noted that as far as pollution from diesel engines is concerned, for the moment, in France, very little importance is given to the chemical composition of the exhaust gases, but rather to the quantity of solid particles contained therein (mainly carbonaceous particles and soot).
In other words, the opacity of the exhaust gases is simply controlled by means of devices called opacimeters or fumimeters ...

http://www.motorlegend.com/entretien-reparation/fluide-lubrification-voiture/les-gaz-d-echappement/8,11764.html

The calculation method:
K = - ln (M1 / M2) / L
with:
L: effective length of the exhaust gas sample,
M1: light power emitted by the source,
M2: resulting power of light received by the detector.

http://www.dgemp.minefi.gouv.fr/metro/approb/decisions/97008520172.pdf

Regarding the opacity of the fumes, there are no chemical measurements of invisible compounds such as, for example, CO2 responsible in part for the effects of greenhouses.
But this question was rather a technical anecdote to better understand what opacity is, It does not call into question the results of the CT.

I do not want to deny the apparently very promising advantages of doping, it is rather the engine manufacturers, the states, the sncf, etc ..., who deny them and I find that more than strange, especially compared to their means and their interests.
The measurements made (consumption / pollution) are certainly true, but are they representative?

Hello

Thank you for the advice, but the school, I went there a little and enough I think to manage to find a job in the sector using my acquired knowledge, This is not the case of everyone, I believe (In principle the one to whom the community has paid for training which it has assimilated and if, in addition, it shows ingenuity, does not take long to be recruited, ... in short).

(finding a job is not difficult but keeping it is something else, I think in your school they forgot to teach you how to live)
Typically French, I don't think that among you you could see the general manager of the biggest steelworks being a simple welder.
Yet Stelco who was the largest steelmaker in Canada are CEO and was a welder .. (with Mittal Arcelor it is another philosophy : Cry: )

Coming back to consumption, what is strange is that the figures reported by the two town halls are very close to the figures that I measure on my car, and the figures provided by others who are not on the forums . (sometimes I understand them not to waste their time on forums )

A guy who has done montages and experiences does not need to read a post for long to understand what is real and what is far-fetched.
I wonder who has to pass on a bench over a long period a system that works? not just a 15 minute
a test that makes like the cultivators a day in the fields and on a car a taxiing of 2 to 3 hours on a highway, there you have figures that you can draw conclusions
Analyzing and improving 30km in city driving, you have to spread it over a year is thousands of km


Now that a guy believes it or does not believe it is not a religion, it does not make a miracle, these long discussion does not bring much
When the argument revolves around the credibility of those who post to know their pedigree, their experience, their education? it just makes blah blah, not constructive ..

Hello

it might be necessary to pass some to the bench, because they largely pollute the forum ...

..............

for Christophe, is there a way to filter for users, polluters, which would clarify the content, because sometimes it's a bit of a jungle!

jeff

ps: I am consulting old subjects dating from 2007 and 2008, no doubts compared to today, it is clear and easy to read, none or practically no spurious messages

CO has no real responsibility for the greenhouse effect ...

Opacity is only used to give an estimate of the level of production of soot (made up of particles of different sizes), and that's it ...
Maybe we can deplore it, but that's how it is.

A full test (for example to check compatibility with Euro standards) costs much more than a simple technical check, around 150 to 200 €.

Exact Bucheron, I meant CO2 as I mentioned above not CO.
dsl, thanks for correcting me.

At 30 March 2009, after more than a year of testing, the observed results are as follows:
- reduction in the average fuel consumption stabilized at 25%: from 7,42 L / 100, we go down to 5,57 L / 100.


Without wanting to criticize this system, I find that the consumption announced for the 306 Diesel is really excessive.

I have a 306D from 1998, I do 6L / 100 (a full of 60l for 1000km) on average and I don't mind my consumption, I drive normally, not bad on the road it is true. To reach such consumption 7,42L / 100, I basically have to do 130km / h on 800km because I saw that it consumes a lot on the highway or exclusively that of the city (it never happened to me too much consumed because of the city).

Moreover it is confirmed by the figures given by:
http://www.autotitre.com/fiche-techniqu ... t/306/1.9d

By being careful, I have already managed to make more than 1050 bollards with a full tank or 5.5l / 100 (since I had to fill up about 58l). [/ Quote]

We never said the opposite but in this case: pkoi it is not factory fitted?


Macro wrote:That said, the results are very honorable ... For an artisanal depollution ... It would be necessary to see with on-board gas analysis benches if the thing is confirmed ...


It's already good to admit it ...

As for the bench, engineers from Douai Mines almost got there, only there was a so-called breakdown of the test bench on the day of the tests ...

See their report: https://www.econologie.com/projet-echo-m ... -3516.html

Debate: https://www.econologie.com/forums/nouveau-pr ... t4255.html (their site is HS because not renewed but I believe that I had saved all the docs on econo ... at the time)

To give grain to the defenders of the big plot, there is no better I think ...

Already answered above: it all depends on the driver ...

a) it's not really excessive for the city
b) it's your car
c) these are Your fuel bills

Good evening

by any chance, a web page that talks about the performance of the 306 diesel, obviously the consumption advertised by Cahors corresponds (before transformation of course).

Have you ever "banged" in your car?


If of course during the first 60km (and 000 sets of tires ...) and, of course, I happened to exceed 3l / 10km (full speed on 100km of highway several times). During this period when I used the vehicle still throttle in stop (because of its modest performance), the average consumption varied from 900l to 7,5l, but, I mainly did mountain road and very little highway.
At 60 km I decided to change my driving, my routes changed, and I also removed the catalytic converter.
Finally, my vehicle passes every year to anti pollution control, compulsory for company vehicles, without problem.
Since then, I have prefabricated the "Gillier - Pantone" assembly but I have not yet had the courage to install it.
